Who it's for

• Sales and SDR teams entering Mexico: "IT consultancies in Mexico City with 11+ employees and a website", "food manufacturers in Jalisco and Nuevo León".
• Market sizing / TAM: every run reports total_matching (all establishments that match), even if you only pull a sample.
• Enrichment: start from a SCIAN segment and feed the list to your enrichment waterfall or CRM.

What makes it B2B

DENUE lists ~6.1 million establishments, and most of them are corner shops run by natural persons. This actor turns it into a company list:

	DENUE as published	This actor
Who	Every establishment, ~79% of them natural persons (no legal name)	Legal entities only, always (no switch: company data only)
Public sector	Mixed in (schools, offices, hospitals)	Excluded by default (exclude_public_sector)
Industry	SCIAN code + Spanish label	Spanish class label + English subsector and sector labels
Size	Text bracket ("11 a 30 personas")	Bracket filter + min_employees + numeric bounds
Phone	Free text	+52 + 10 digits, junk dropped
E-mail	Free text, typos, Gmail/Hotmail/Prodigy	Validated, lower-cased; freemail/ISP never used as a website
Website	Free text (WWW.X.COM, Facebook pages)	https:// URL; social pages split into social_url; website_guess from corporate e-mail domain
Branches	One row per establishment	Optional one_per_company (largest establishment per legal name)

Field notes

• Legal entities. INEGI publishes the legal name (razón social) only for legal entities and usually strips the corporate suffix (S.A. de C.V., S. de R.L., …). is_legal_entity is true when the name carries a legal form, or when a legal name is present and doesn't look like a person's name or a placeholder. legal_entity_basis says which rule fired (every output row carries it). Rows with a person-like name are treated as uncertain and never returned.
• website is what the establishment declared to INEGI. website_guess is https:// plus the corporate e-mail domain; free-mail, Mexican ISP (Prodigy/Telmex, Axtel, izzi, Megacable…) and typo domains are never used. Neither is verified by an HTTP request, so check before using at scale.
• scian_label_en is the English label of the 3-digit subsector; scian_label_es is INEGI's official 6-digit class label. SCIAN is Mexico's NAICS; codes are SCIAN 2023.
• registration_date is the month the establishment entered DENUE, not its incorporation date.
• Rows are establishments. A chain appears once per branch; use one_per_company to collapse.

Data freshness

DENUE edition 05/2026 (published 2026-05-20; Sinaloa corrected 2026-07-01). INEGI refreshes DENUE roughly yearly, mostly for large establishments. Every row carries data_as_of and source; the run log and the OUTPUT record also show the data_as_of of the release that was queried.

Privacy

Company data only. Establishments of natural persons (personas físicas) and rows that are not a confirmed legal entity are never returned, and there is no input to change that (legal_entities_only: false is rejected with an error). You are responsible for using the data lawfully (LFPDPPP, anti-spam rules, opt-out requests).

Pricing

Pay per event:

Event	When it's charged	Price
company-result	Once per company row returned in the dataset	$3.00 per 1,000 results (placeholder)

Set a maximum cost per run and the actor stops pushing rows when it's reached.

FAQ

Is this the official DENUE? It is built from INEGI's open bulk download, cleaned and enriched. It is not an INEGI product and INEGI does not endorse it.

Why do some big companies have no legal name? Some establishments are registered by INEGI without razón social. Without it we can't tell a company from a natural person, so those rows are not returned.

Can I look up an RFC? DENUE does not publish RFCs.
